Battery Generators : Best Battery Generator Buying Guide

Battery Generator : A Battery Generator is a Portable Battery Powered Outlet. It is a Battery surrounded by an outer casing of electronics.

Portable Battery Outlet : Battery Generators are a Portable unit usually with AC Power outlets, USB outlets and DC power outlets that can supply power to smart phones, laptops, Tablets and CPAP machines.

Power Generator Battery : The battery inside the Power Generator is usually a Lithium Ion or an AGM battery.

Charging your Battery Generator : You have to keep the internal battery charged for you to enjoy the benefits of having a Portable Battery Outlet.

Best Battery Generators : In the next section we go inside the Battery Generator. However, for the impatient, here are the top Battery Generators in the market today.

You can charge the battery directly from a wall outlet. Some Battery Generators can also be charged using a Car Charging outlet or Solar Panels.

So, don't be surprised if someone refers to your Battery Generator as a Portable Solar Generator.

The Battery inside the Battery Generator is a DC energy Source. The DC power from the Battery has to be transformed into AC before you can use it as a Portable Battery Outlet.

Inside a Battery Generator

Charge Controller : Every Battery Generator has an inbuilt Charge Controller. This charge controller keeps your the inbuilt Battery of your Battery Generator in top shape. It prevents overcharging or over discharging and ensures you get the longest possible life for the battery.

Inverter : Another essential component of a Battery Generator is the Inverter. This controls the conversion of your Battery's DC energy into usable AC power though the Portable Battery Outlet's AC plugs.

Power Generator Battery : The Charge Controller, The Inverter and the Battery are all artfully designed into a compact power generator battery unit that is easy to carry around. The external outputs including the AC outlets, USB outlets and DC outputs are all neatly aligned on one side and the inputs for charging are usually in a separate area of the Battery Generator.

What Size Battery Generator do you need?

While deciding on the best battery generator : you need to decide on the correct size for your needs. Every generator is rated for power output.

The smallest battery generators start at 100 watts and they go up all the way to around 600 watts. The comparison chart above lists the most popular and reliable models and has links to reviews as well.

Battery Generators larger than 600 watts are in the heavy duty range. Many manufacturers like to present them as portable solar generators.

However, they are difficult to lug around as the bigger size of batteries and hardware make them easier to keep and maintain in one place rather than have them move around with you during your camping trips.

But if you want to look at all the options, a complete list of solar generators starting from the portable and going up to the heavy duty solar generators are available in this comprehensive listing of all solar generator sizes.

Battery Generator Size Calculator

STEP 1. Look at the table below and make a list of everything you would want your Portable Battery Outlet to power

While you are selecting the appliances you want to power, keep in mind that portable battery outlets are good only for smaller devices and appliances. For larger appliances you should either consider Heavy Duty Solar Generators or a Standby Generators which can power your entire home

STEP 2. Now to size the portable battery generator ?

Lets look at the list of devices or appliances you selected in Step 1. Here is an example of what your list might look like :

** Surge Watts or Surge Capacity of most Power Generator Batteries are the same as their power capacity unless surge watts are specifically mentioned. For example since the Suaoki 400 has a power capacity of 444 watts, its surge capacity is also 444 watts.

Don’t worry about surge watts if you are looking only at Portable Solar Generators.

KP 601: Customer Review

Kevin M, AZ : The KP601 is perfect for my needs : The Battery Generator charges our cell phones and tablets for over a week. It powers my LED light for a few weeks without a recharge and it an excellent battery back-up for my amateur radio.

The KP601 Battery Generator does not have AC outlets – which is great as it reduces the weight of the unit. An external 12 volt inverter is the way to go – just $30 for my one. DC to AC inverter built into the pack. Kudo’s.

The solar panels provide ample charging power and I can use a 12 volt fan or refrigerator, with the KP601. And its a really good looking portable solar power generator.

Anker 400w

The Anker Powerhouse 400 portable AC Power Supply cum Battery Generator is in a league of its own.

This pint sized battery powered generator is a monster in disguise. Its new generation high efficiency lithium ion battery makes it super light without loosing any power. Add an external panel and voila, you have a monster portable battery power system.

A champion battery powered generator that can power a small fridge or a CPAP machine with ease.

Anker 400 Customer Review

Dude @ MI : The Anker Battery Generator ran my Respironics Auto 50 series CPAP without the humidifier for 8 hours on the AC plug. The Anker Powerhouse used 6 hours of capacity and still had 24 hours of charge left on it. I ran a small fan, the CPAP and charged my phone and the unit ran for 10 hours.

But, when I tried it using a DC adaptor, instead of running it off the Anker’s AC outlet, it used just 1 hour of charge. Amazing I can use the Anker now as a Power Backup source.
